When Breath Becomes Air

by Paul Kalanithi

If the unexamined life was not worth living, was the unlived life worth examining?

Science is based on reproducibility and manufactured objectivity. As strong as that makes

its ability to generate claims about matter and energy, it also makes scientific knowledge inapplicable to the existential, visceral nature of human life, which is unique and subjective and unpredictable. Science may provide the most useful way to organize empirical, reproducible data, but its power to do so is predicated on its inability to grasp the most central aspects of human life: hope, fear, love, hate, beauty, envy, honor, weakness, striving, suffering, virtue.

Human knowledge is never contained in one person. It grows from the relationships we create between each other and the world, and still it is never complete.

Most ambitions are either achieved or

abandoned; either way, they belong to the past.

When you come to one of the many moments in life where you must give an account of yourself, provide a ledger of what you have been, and done, and meant to the world, do not, I pray, discount that you filled a dying man’s days with a sated joy, a joy unknown to me in all my prior years, a joy that does not hunger for more and more but rests, satisfied. In this time, right now, that is an enormous thing.
